Avatar of fire keystone should have visual effects

Am I the only one who finds it strange that a special keystone that turns you into an elemental with 100% fire damage has no visual effect?

I don't know if it's a matter of preserving the character's visual identity or not, but there should be at least a subtle visual effect.

I was playing in act 3 and I got a buff called "Ignorak" (something like that) that made you enveloped in fire, I thought it would be ideal for the Avatar of fire keystone to make you like that, it's an effect that already exists in the game.

This is just my feedback from a fire warrior enjoyer.
